youtube - ffprobe or avprobe not found. Please install one

Question

I want to add tags to mp3 converted by youtube-dl & ffmpeg:

youtube-dl -o '/Output/qpgTC9MDx1o.mp3' qpgTC9MDx1o -f bestaudio --extract-audio --metadata-from-title "%(artist)s - %(title)s" 2>&1

I have this error in the output result:

[youtube] qpgTC9MDx1o: Downloading webpage [youtube] qpgTC9MDx1o: Extracting video information [youtube] qpgTC9MDx1o: Downloading js player en_US-vfluGO3jj [youtube] qpgTC9MDx1o: Downloading DASH manifest [download] /var/www/vhosts/mp3-y.com/httpdocs/Mp3_Output/quick-mp3.com-JALAL-EL-HAMDAOUI-2007-ARRASSIATES-VOL2-F1P-9CDoxlQ.mp3 has already been downloaded [download] 100% of 13.43MiB WARNING: qpgTC9MDx1o: writing DASH m4a. Only some players support this container. Install ffmpeg or avconv to fix this automatically.

Answer 1

Make sure you have the last version for youtube-dl

sudo youtube-dl -U

after that you can solve this problem by installing the missing ffmpeg on ubuntu and debian:

sudo apt-get install ffmpeg

and macOS use the command:

brew install ffmpeg
